it is possible to wide the range of powerconsumtion on this switch from 15.4W up to 20W? We will rollout some accesspoints with 2 radiomodules on CISCO AP1252, but the Powerconsumtion of this AP then ist 18.5W. The max allowed from firmware is 15.4W like 802.11n-standard.

I am trying to get QoS for my VoIP system setup on several SGE2000p switches and have got a question...How do I define the ACL for RTP? As far as I can tell it will not let me enter a UDP port range for the RTP traffic... And I cant imagine creating rules for each port would be very effective either. So, how can I define an ACL to cover the RTP traffic so I can classify it?

I would then create the relevant VLAN’s on the switch. Can each VLAN be assigned an IP address and allowing me to be able to add a static route on the router pointing the traffic for the Guest VLAN back to the switch?
View 1 Replies View RelatedI've got multiple SGE2000P & SGE2010P switches
Originally I was happy just set them all up in a stacked ring configuration. However I've become aware that my back bone fibre links are contantly pushed to their max.
So I've decided that I should change this configuration and unstack the switches and make them all stand-alone units. and I'll configure 2 cable LAG links between all my switches Theorically I should now get 2GIGs between each switch and to complete the ring in my network for redundancy I'll turn on Spanning tree.
However I've tested the speed and I just can not seem to get a LAG connection with 2 x 1gig cables to push more data than a single link 1gig link cable would.
My test enviroment(not using fibre optic cables just cat5e copper cabling):
4 x pc's(all gigabit network cards)
2 x sge2000p switches
PC1 ---(1G eth)--- /---(1G eth)--- PC2
[SGE2000P]===(LAG1 2x1G cables)===[SGE2000P]
PC3 ---(1G eth)---/ ---(1G eth)--- PC4
If I send files from PC1 & PC3 simultaneously to PC2 & PC4 They don't transfer faster than if I I just use a single 1GIG Link cable
looking at the LAG configuration it shows both cables are connected & the LAG looks like it's working. But it really doesn't seem to be running at the expected 2GIG?
The LAG fail over seems to work fine if I remove either of the 2 cables from the LAG the link continues to work. (sometimes it will drop a ping when removing or readding a LAG cable)
I'm planning to separate voice and data traffic with two vlans. I have a COR switch catalyst 3750, a UC560 for VOIP with SIP trunk and SGE2000P as access switches. The thing is i had configured VLAN1 (data vlan) and VLAN8 (voice vlan), i've created the vlan 8 in the database on 3750 and let pass those vlans through a TRUNK port. In the SGE2000P configuration i've created the VLAN8 and the the ports as trunk for letting pass the two vlans for the PC and the IP phone. This works but some phones aren't registering, and for example i've unplugged a register phone and plug and doesn't registering anymore.

I'm using a stack of four SGE2000P switches for a PoE video camera system. I've got the cameras in a VLAN and everything's working fine.
I'm wondering, though, is there a way to find out what data rate the stack interfaces are working at (since it's going over cable infrastructure we put in ourselves), and also what percentage of that bandwidth is being used? I don't see anyway to get to those interfaces from the main page, and I wasn't able to find a way to do any sort of percentage thing even on a regular interface.
Is it possible to configure LACP etherchannel to a Catalyst 3750? Playing around with the SMB switches for the first time.

View 1 Replies View RelatedI am having problem setting up SGE2000P switches to work with my default data VLAN and additional voice VLAN. I am configuring it to pick IP address for phones from voice VLAN which is working fine but when I connect a PC on phone port it is also picking up an IP from Voice VLAN while default VLAN is data with different scope of IP.
I pack these switches and purchase ESW 500 series. I have ESW 500 at another client and they are working fine out of the box but this guy is giving me hard time.
Currently, we have a plain network and we are planning to 'upgrade' it a little. We want to implement VLANs to separate wireless clients, workstations + servers and infrastructure devices form each other.As of now, we have no VLANs, and no managed Switches. We only have an RV016 that handles two ISPs and a 3rd party connection service to the office branches ( I belive they're using Frame Relay, but as far as we know, we are not concerned since we cannot touch their devices)
The reason behind the title, pointing towards the famous SGE2000P, is that my workplace is located in Argentina... and we don't have as many choices as some of you guys have ! In fact, I was unsuccessful trying to get a Cisco partner to contact me. We would like to replace the RV016 with a cisco 1941 (and a HWIC switch card).
So, back to business..! Assuming we will be using the SGE2000P switches, I was thinking about setting VLANs using 802.1Q through seven of these switches, along with a 1941 Cisco router. I'm expecting the 1941 to handle load balancing between both ISPs and the 3rd party link. Now, as for Inter VLAN routing, I would like to have gigabit traffic between VLANs.
Is it possible to use one SGE as Layer 3 mode to hande inter VLAN traffic (gigabit speeds) while using the 1941 as a end point device to reach internet (using PAT) ?Would you suggest me to use the 1941 for Inter VLAN routing, despite the 10/100 limitation(*) and use all SGE's in L2 mode? We need two ISPs, a third link for the FR connection, and finally the LAN interface. As far as I know, I'm limited to the gigabit builtin interfaces for WAN purposes, am I right?
I'm working with a customer who has an SGE2000P and a Catalyst 2960 to setup and configure a single mode fiber link. The SGE2000P has an MFELX1 fiber GBIC and the 2960 has a GLC-LH-SMD GBIC. When I have the customer plug in his fiber, there is a power light that comes on on the MFELX1 GBIC. Neither GBICs/switches show that a link or activity is occurring, but the presence of that light makes me think that they are connecting somehow. Are these two switches/GBICs compatible?

View 4 Replies View RelatedI'm having an issue with a 1252 LAP that is connected to the WLC over a WAN link.Basically, it won't associate. The following is taken from a console into the LAP:
*Mar 1 00:00:07.799: %LINK-3-UPDOWN: Interface GigabitEthernet0, changed state to up
*Mar 1 00:00:08.799: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0, changed state to up
*Mar 1 00:00:26.851: %LWAPP-5-CHANGED: LWAPP changed state to DISCOVERY
*Mar 1 00:00:27.003: Logging LWAPP message to 255.255.255.255.
[code].....
The ap-manager interface is configured correctly and there isn't a duplicate IP address. The LAP was initially stand alone and was converted to LWAPP.The MTU over the WAN link is 1500 bytes.All I'm getting from the WLC debugs is:
Mon Jul 20 11:42:59 2009: 00:22:xx:xx:xx:xx Received LWAPP DISCOVERY REQUEST from AP 00:22:xx:xx:xx:xx to 00:19:xx:xx:xx:xx on port '29'

Mon Jul 20 11:42:59 2009: 00:22:xx:xx:xx:xx Successful transmission of LWAPP Discovery Response to AP 00:22:xx:xx:xx:xx on port 29
So basically the join messages don't seem to reach the WLC. In fact they don't even seem to reach the local router on the remote subnet. The discovery packets are seen on the local router but the joins don't seem to appear at all.I'm not sure if it's a latency issue. Average latency over the WAN link is under 70ms.I'm assuming the certificate on the WAP is MIC and the MAC details have been entered into the WLC AP Security policies for authentication. I'm not seeing any debugging messages relating to bad authentication at all.I can't debug from the LAP as it's LWAPP, obviously.We're running WLC version 4.2.130.0.

View 1 Replies View RelatedI have Cisco 1252 APs in my network and also a WLC with software 7.0.98.0 and a WCS system. In certain areas I have an SSID with 2 or more APs configured as part of the group. Some users are connecting to the SSID on the weaker AP when there is a much stronger signal available from a different AP.I have looked into this issue before and have been told it's a porblem with the client's Wireless NIC or the drivers. The issue is I'm using the most updates drivers on some users and it makes no difference. Although it may be a problem with my clients I need to fix this on Cisco's AP side. What are my options? I believe MAC filtering is only per SSID so that would defeat the purpose, can I filter by specific AP and still allow the user to connect to the SSID? Or should I seperate the APs from the 1 SSID and create multiple SSIDs so the user can select the stronger network?

View 4 Replies View Relatedwe want to have full wireless coverage in a big warehouse (120mx90m) and 15 meter Height that will be having big racks (14 meters height) and 2 meter between the racks and the rack itself is 1.5 meter (2 rack back to back), now we will be having scanners and we need to make sure the wireless is covering everywhere.Where is the best place to put the AP, Ceiling? How Many APs per row ? each row will be around 60 meters length.
Is AP 1252 a good choice? The scanners are a/b/g.What i'm thinking of is to put 1 AP per row mounted on the ceiling and antennas facing down because it is hard to mount the APs between the rack because of the automated racking system.
Currently my company has 1 primary SSID that is used throughout both floors of the building. We have 1252 LAPs which have 2.4 and 5Ghz antennas. I'm not sure if this issue is only with XP or perhaps it's the computer's drivers but we run into problems with end users going to a different location and having a very weak signal or nothing at all, yet coverage is fine. I believe the problem is the end user's machine selecting the strongest signal and it I have the feeling that switching bands isn't being done as it should when it's in range. So my question,
Should I split up our 1 SSID and created multiple SSIDs according to the location and include 5Ghz or 2.4Ghz in the SSID name so it's easier to ensure that users are connected to the proper signal? I want to ask if multiple SSIDs would still enable users to freely roam (as long as the ssids are configured) throughout the building without noticing a loss of signal but currently just having 1 SSID isn't really enabling people to freely roam around without connection issues.I don't believe having multiple SSIDs will be useful for the computer's choose their connection any more efficiently but allowing the user to manually see what they're connected to and pick something better according to their location.
I am configuring a mobile van that is used for a mobile health clinic to drive to several locations and when pulling into an allocated parking spot the van will connect via wireless automatically. I am using autonomous 1252 AP's and am considering either briding or workgroup bridging.
The issue I am encountering is that the AP inside a van is a router that has to do DHCP across the wireless and because the ethernet interface between router and AP in the van never goes down the router does not know to re-DHCP. I remember from way back there was an IOS command to track a serial interface and drop the ethernet if the serial link goes down. Is there an equivalent command for AP's to drop the ethernet interface if the radio interfaces go down?
I am using two Cisco Aironet 1252 (cisco AIR-AP1252AG-A-K9) to setup a point to point link (one is configured as root bridge and is as a non-root bridge). Both Aironets are running software version Version 12.4(25d)JA.
Is there a way that I can that I can perform an antenna alignment test on the Aironet that is configured as a non-root bridge?executing the following command dot11 dot11radio 0 ? does not show the antenna-alignemnet option.
I would like to add an additional antenna to a 1252 LAP but I'm unsure of a few things...
I know this LAP currently has at least a yogi directional antenna (AIR-ANT2410Y-R) and also a ( AIR-ANT2485P-R) connected to it. The access point is in a ceiling so I cannot view the connections but according to this data sheet, { URL } each of the antennas I've specified require 3 per AP. I am only aware of 1 of each being used so not sure why 3 would be required?
Also on my 1252 1 side has 3, 2.4Ghz connections for antennas, TX, TX&RX, and RX. If I want to only use 1 AIR-ANT2410Y-R, would this be connected to the TX&RX port? Do all antennas support transmit and receive or are there some that only support TX and others that only support RX or is this based only how you configure the antennas? On the other side of the access point there are 3, 5Ghz antenna connections.
I found a few older forum posts and documents online discussing how to create multiple SSIDs on 1 1252 AP using the WLC and they state that VLANs are needed for the interface and then I've read that multiple SSIDs on 1 interface are also possible. I'm not sure on how to actually configure this. I would like my 2.4Ghz radio on the 1252 to be associated with the current SSID in production and the 5Ghz band associated with another SSID that's in production. I couldn't find an option in the WLC or anything stated in the documents I've read about how to associate the radio band with the SSID.
